Network Redundancy

For network redundancy a control station can reach a substation via 2 paths.

Both the control station and the substation can have 2 different IP addresses. Without special network routing, 2 separate networks should exist, within which both the substation and the control station each have 2 interfaces.

There are 4 possible variants of network redundacy:

• Network Redundancy with 2 separate Networks
• Network Redundancy with 1 Network and 2 ETHERNET Ports in Substation
• Network Redundancy with 1 Network and 1 ETHERNET Port in Substation
• Network Redundancy with 2 ETHERNET Ports in Substation
